FAQs
What is the color change range for phenol red?
Phenol red transitions from yellow at pH 6.4 to red at pH 8.2, with intermediate shades of orange in between.
How do I prepare a 1% phenol red solution?
Dissolve 1g of phenol red powder in 100ml of distilled water or appropriate buffer solution, then sterilize if needed for cell culture applications.
Can this be used in cell culture media?
Yes, this ACS-grade phenol red is commonly added to cell culture media to monitor pH changes during incubation.
What’s the shelf life of phenol red powder?
When stored properly in a sealed container away from light and moisture, the powder remains stable for 2–3 years.
Is this product suitable for educational labs?
Absolutely. The clear color transition makes it excellent for demonstrating pH concepts in school and college laboratories.
